摘要
The sporadic fault ascertaining procedure is applicable to telecommunication systems esp. telephone networks. Every interference in the connecting process is recorded in a fault registering installation. The faulty appts. concerned is indicated as well as its switching condition at the time the fault appears. These recordings are sorted in a computer and compared with the fault data of a comparator memory. The recordings of the fault registering installation (P) are fed to an evaluator (A) constructed as a computer at stipulated intervals. The evaluator (A) is coupled to a memory (S) storing the installation data. The evaluator (A) contains a comparator for appraisal of the register recordings against the previously known ault possibilities and limits stored in the memory (S).
